When does it get Dangerous 400? 500?

[bigcat]

I'm not sure what all is done with the internals of the new Roush P51A, but it will be over 510 HP and will have the full 3/36 warranty.

its got all the internal goodies....

It was determined that the only way to give the P-51A moniker its due was to completely break into the 4.6L, 3V and rebuild several of the functional internal components, which include a forged steel eight-bolt crankshaft, forged aluminum pistons with increased dish to lower the compression from 9:8 to 8:6, and forged steel H-Beam connecting rods. These upgraded parts were necessary for the stock Ford engine (which comes with 300 horsepower from the factory) to be able to withstand the additional power generated from the newest iteration of the legendary ROUSHcharger* supercharger system.​

a guy i know has a few bolt ons and turbo on his 07 GT Auto with STOCK long block, heres the numbers

*1st pull made 492 rwhp ~ 468 ftlbs @ 10 PSI'S thru the factory automatic tranny and converter

*2nd pull made 608.96 ~ 561.42 ftlbs @17 psi's with C16 and only 15* of timing. Basically a very safe tune with the air/fuel a solid 11.4 to 11.6 across the board.

at 9 psi on 20" his best time was a 11.947 @ 121.75 w/2.098 60ft

next time out he's going to run slicks and see what lests go.
